Orthodontic device and orthodontic method

Abstract

An orthodontic device and an orthodontic method that can prevent an orthodontic treatment from being eccentrically performed while aligning straightly tooth. The orthodontic device includes teeth-attachment unit attached to an orthodontic tooth object; and hook member provided in the teeth-attachment unit and having a connection part of traction unit for orthodontic treatment that is located in the vicinity of a center of resistance (CR) of a tooth. In addition, the orthodontic device includes teeth-attachment unit; and hook member provided in the teeth-attachment unit and having a connection part of traction unit for orthodontic treatment that is located in the vicinity of at least gingiva. Since the teeth-attachment unit of a bracket or a button is substantially horizontal to a traction line of the traction unit, it is possible to perform the orthodontic treatment effectively without eccentric phenomenon in which the tooth and a dental root are tilted.

Description

TECHNICAL FIELD[0001]The present invention relates to an orthodontic device and an orthodontic method capable of straightly aligning teeth, and more particularly, to an orthodontic device and an orthodontic method in which a connection part (connection point) between hook member provided at teeth-attachment unit of a bracket or a button (for orthodontic treatment-straitening irregular teeth) attached to a tooth and traction unit providing orthodontic force is located in the vicinity of a center of resistance of the tooth or in the vicinity of at least a gingiva, thereby performing the orthodontic treatment effectively without eccentric phenomenon in which the tooth is tilted during orthodontic treatment.BACKGROUND ART[0002]Irregularly arranged teeth, malocclusion (the state where occlusion is not matched), or facial protrusion results from teeth and stomatognathic face do not have grown up in a proper place due to growth abnormality of the teeth, growth abnormality of a jaw bone, ba...

AI Technical Summary

Benefits of technology

[0026]According to an orthodontic device and an orthodontic method of the invention, since a connection part of traction unit connected between anchor member and a bracket or a button of teeth-attachment unit is located in the vicinity of a gingiva corresponding to a center of resistance of a tooth in consideration of the total length of the tooth and a dental root, an orthodontic treatment is performed by pulling out the teeth and the dental root in a horizontal state with respect to the anchor member without eccentric phenomenon, thereby improving orthodontic properties.

[0027]In addition, since the connection part of the traction unit and the hook member extended from the orthodontic device of the bracket or the button is located in the vicinity of the gingiva, the orthodontic treatment is easily performed, and the exterior exposure of the connection line between the anchor member and the traction unit can be reduced. Therefore, according to the orthodontic device and the orthodontic method of the invention, the appearance after the orthodontic treatment is aesthetically beautiful.

Problems solved by technology

Irregularly arranged teeth, malocclusion (the state where occlusion is not matched), or facial protrusion results from teeth and stomatognathic face do not have grown up in a proper place due to growth abnormality of the teeth, growth abnormality of a jaw bone, bad habit such as finger sucking, during infant, bad dietary habit, and / or inheritance.

The irregular arrangement of the teeth, the malocclusion, or the facial protrusion may result in passive interpersonal-relations and also reduces a uniform pulverization of foods that is a basic function of the teeth.
